had hi, how you doing? >> you act like this is some big joke here. >> these were people that were in the shadows and now they have been exposed. >> my seasoned detectives and myself were shocked at what we saw happening. >> i believe that we would have had some young child sexually abused. >> "dateline's" groundbreaking series is back. >> i'm not really a predator, sir. >> you are not a real predator? >> no, sir. >> just a pretend predator? >> men targeting children online. >> a field trip in florida. >> so you drove 60 miles to see a 14-year-old girl? >> a repeat rendezvous in california. >> you know, you look familiar to me. >> oops.

>> and arrest after arrest after arrest. >> oh, my god! >> put your hands up. >> the latest on the series that's changed laws and lives. >> if "dateline" had not been there, there could have been 51 victims. through a click of a mouse, your child can go visit and talk to people they'd never talk to. >> it's time for all of to us wake up. >> chris hansen goes coast to coast "to catch a predator." thanks for joining us. i'm stone phillips. >> and i'm ann curry. this time we're in long beach, california. >> this time someone's gone online to post a warning our hidden cameras are in the neighborhood. but think that stops these men? a reminder some of what you are going to hear and see is explicit.

here's chris hansen. >> what do we have coming up right now? >> that's our avalanche. that's our 12:30. like 29 years old. >> we have always been aware that the men coming into our undercover houses could be dangerous. >> stay there, we don't want to send you out yet. >> but as we set up our "to catch a predator" operation in long beach, california, the very first man who arrives has us especially worried. >> whoa, hold on, here he comes. head to position three. >> this 29-year-old, an unemployed computer technician, uses the frightening screen name can i rape you anally? he thinks he is coming to meet a girl who says she is 13. >> open up the door. >> what he apparently doesn't know is he has really been chatting with an adult decoy from perverted justice. that's online watchdog group dateline uses as consultant to do what it normally does, go into chat rooms, mostly on yahoo and aol and set up computer profiles and, in this case, pretend to be children under the age of 14 who are interested in sex. >> okay. that's cool. >> in his online chat he tells the decoy maybe we should hook up and says he would like to have anal sex with her.

the decoy says, ouch, i think that would hurt a lot. warrecker responds, yeah, but it 's a good pain. >> now is he at the door being met by a youngish looking 18-year-old decoy playing the girl who is supposed to be home alone. >> can you sit down? >> it's time for me to have a chat with him. >> we have a lot to talk about. >> though my arrival doesn't seem to faze him one bit. >> this is punch, right? >> yeah. >> what are you doing here? >> hanging out. >> hanging out? >> and i knew this was a setup because this was too convenient for this. >> what was too convenient? >> the chat room and just talking about everything that she did. >> how old was this girl you were talking to? >> she said she was 13. >> 13. and how old are you? >> i'm 29. >> you thought it was okay to come over here and meet a 13-year-old girl at the age of 29? >> and hang out, yeah. >> that's all you were going to

do was hang out. >> these what i told her, yes. >> but remember we have his chat log that he writes to some 13-year-old female, i like rape. she responds creepy. he explains he doesn't really want to rape her, just rough sex. i would want you to resist and pretend you didn't want it and stuff. >> what kind of a guy has a screen name can i rape you anally? >> it gets responses. >> do you think rape is okay? >> no. >> why do you do this? >> it's just i like to put myself in that role and talk about it, you know? >> he also asks online if he could tie the girl down while they are having sex. it gets scarier when he goes on to add, i might want you to cut you a little, suck on your blood, laugh out loud. >> a trait that i look for is, you know, they enjoy a little bit of pain here and there, you know. >> you have had girlfriends who enjoy a little bit of pain? >> yeah. >> how many times have you had a

conversation like this and actually met somebody to fulfill this rape fantasy? >> never. i thought it would be cool to hang out. >> you thought it would be cool to come over here after having a chat somewhat like this -- if i wanted to bend you over and just shove it in your [bleep] it hurt pretty bad you wouldn't do anything, would you? yeah, i would scream and try to hit you. you act like this is some big joke here. >> sir -- >> those are your words, not mine. i'm not making this up, right? this is stuff you said. >> that's correct. >> to somebody who said she was a 13-year-old girl. >> yes. >> what do you for a living? >> actually right now i'm unemployed. >> unemployed? >> i got a small inheritance a year ago and sort of took a break. i'm almost out of money now. >> time to go back to work. >> it's time to go back to work. >> he tells me he has brought along a scary movie to watch with the girl, video camera and lubricant. >> is this any way for a 29-year-old man to behave? >> no. >> have you ever watched "dateline" nbc? >> sometimes. >> i'm chris hansen with "dateline" nbc.

hi, how are you? >> this is the third time we've set up an undercover house in california. for the long beach police, it's a big operation. sergeant lee debraybander is in charge. >> just playing this alone was a huge event. we had surveillance all over the place in undercover vehicles. we had the arrest team in place. we had in excess of 25 officers at any given time. >> it's challenging for us as more potential predators become aware of our investigations. look at this posting on the craigslist web site warning predators that "dateline" is in long beach. on the first day, some show up but never come in the door. >> will! all right.

>> like this man who doesn't like what he sees and pulls a u-turn even as the decoy waves him in. >> i think is he a goner. do you want to sit down and get a drink? i'm going to get something really quickly. i will be right back. >> yeah, sure. >> did you bring everything with you? >> yeah. >> awesome. i will be right back. >> this man might have got an look at our camera crew behind that curtain. >> he is running. he is leaving. >> can you do me a favor, though, really, really quick? you can pour me a drink and i will be right back? like two seconds, i promise, stop, don't you want to hang out in the hot tub? >> no. >> or it could be that they have seen our investigations and become suspicious. >> all right. police. >> oh my god! >> put your hands up. >> no! >> oh my god. >> drop to your knees. >> coming up the driveway. in the case of this man, we think we know exactly why he doesn't come in the house.

41-year-old matthew bland, screen name blandmatthew, chatted online with someone who says he is 13 years old. bland asks the boy, really an adult decoy, if he has ever had sex before and explains the other sexual acts he says he will perform on the teen. he also sends along a picture of his genitals. but when bland approaches our house, hoping to meet a boy, we mistakenly send our female decoy to meet him. >> hi, how are you? >> is timothy here? >> timothy? >> yeah. >> i don't think so. >> maybe i got the wrong address. this is 5278, correct? >> yes. >> huh! my apologies, i must have gotten the wrong address. thank you. >> he has the right address, but, remember, according to his chat he was expecting a young boy. bland tries to leave, but the long beach police have another plan. >> put your hands up. palm beach police, put your hands up. stop right there. stop. put your hands all the way up. straight up. turn around. >> even though bland didn't come inside, his explicit online chat and showing up at the house are enough for him to be charged

with one count of an attempted lewd act upon a child. he later pleaded no contest. >> i think this is our musician, sugar davis. >> at our undercover house other men keep arriving. >> his name is matty. >> this is matthew nash, a 36-year-old musician, screen name sugar davis. he drove about an hour to get here. >> how are you doing? >> not bad. >> good. >> nash was told he was chatting online with a 13-year-old girl. he talks about getting naked in a hot tub with her, smoking marijuana, and putting oil all over each other's bodies. that's apparently why he has decided to come inside. >> come on in. are you excited? yea! i'm excited. >> yeah. it was definitely a long drive, you know, coming down here. >> did you bring any weed? >> huh-uh. >> no? >> no. >> why? >> you didn't bring your drums? >> no.

>> why don't you have a seat over there. >> no. >> i need to talk to you for a second, sir. >> huh-uh. >> outside the long beach police are waiting. at the processing center, investigators find condoms, baby oil and a vibrator in that bag nash was carrying. and he tells the police he's married. >> how long have you been married? >> 13 years. >> ever been caught doing this before? >> no. >> got any kids? >> no. >> ever been caught in this behavior? >> yes. >> he also tells police he and his wife have been to counseling because he has been caught online talking about sex. >> detectives say this kind of arrest really impacts the suspect's fami suspects' families. >> those are the people i feel sorry for. they had no idea it was totally out of their control. because of the actions of this one person, you know, they are affecting all these other people who they are supposed to love and care for. >> nash pleaded no contest to one count of an attempted lewd act on a child. >> okay. go out to position two and wave

him in. >> in the meantime, it's getting busy at the house. and the men who show up are a little more willing to stay a while. like this 24-year-old driving up in his customized nissan altima. >> hey, come on in. sorry, i still have to do my hair. just have a seat. can you get me a drink? >> he works installing stereo systems, chatted online using the screen name nismo 0507 with a girl who says she is 13. he asked if she is a virgin and tried oral sex. he says he will lick her all over her body. >> i will be right back, all right? >> all right. >> that's quite a car you've got out there. >> thanks. >> why don't you have a seat. what do you got going on today? >> nothing. just hanging out. >> hanging out? and you were going to come here to hang out today? >> well, yeah. i got to go to my friend's house after. i have got to pick up my stuff. she told me she lived down here

they're in my car. >> you have condoms in your car? >> yeah. what does that say about your intent here? >> i wasn't -- if i was going to bring condoms, i should have just brought them. >> or you can see how things go and go out to the car and get them in case somebody caught you here and you had them in your pocket. >> right. >> what do you think should happen to you? >> i really regret this. >> you regret it? >> right. >> do you ever watch television? >> most of the time i'm working. >> well, something you've got to know. and that is i'm chris hansen with "dateline" nbc and we're we're doing a story on adults who try meet kids on the internet for sex. >> he leaves us with an apology. >> it's not right to just go in and talk to any young girl or person. >> just like the other men, he will be charged with one count of an attempted lewd act upon a child. he later pled no contest. >> i would ask you to go out the back way. >> "dateline" security team asks him to go out the back door, that's because right out front is the next man you are going to meet. >> sir, please. >> i want to show you something. >> sir, please. >> coming up, this man has a

good reason to cover his face. and do you know what the show is called? >> yes. >> what is it called? >> "dateline." >> "dateline." and there will be other men. some who apparently want to make a day of it. this 44-year-old father of three thinks he is staying for lunch. >> did you bring sandwiches? >> sure. >> awesome. i'll be right back. >> okay. i'm not going to be able to do my job. but once i take advil, i'm able to finish out strong. it really works! [ laughs ] [ male announcer ] make the switch. take action. take advil.

he's sitting in the car in the front. >> it's busy at our undercover house in long beach, california. >> okay, he's getting out of the car. >> just stay tight and we'll go to the front door. >> remember, we asked our previous suspect to go out the back way so he wouldn't scare off our next visitor. >> hi, how are you doing? come on in. >> he is paul clementi, a

22-year-old college student from san diego. he spoke online with someone he thought was a 13-year-old girl. at first he says she's too young but soon asks her if she's had sex and what positions she's used. finally, he gets down to business. >> when is a good time i can come to your house? of course when your mom's not around. i'm asking when, so we can go out. >> he asks if she has had sex in a hot tub but the decoy answers yes. he writes back. >> you are making me horny. >> for good measure he sends along this picture of his penis. then he tells her something that surprises us. >> you're going to be my first. >> that's right. he may think she's 13. but he's the one who says he's a virgin. now the 22-year-old virgin is in the house. >> all right.

can you pour me a drink really fast? >> sure, no problem. >> thanks. awesome. yeah. i'm just going to get my hair ready. i'll be right back. >> take your time. >> i'm excited by the way. >> me, too. >> you are excited, too? how are you doing? >> i'm sorry.

>> sir, please. >> why did you think that was an okay thing to do? >> sir, she said it's okay. >> she said it's okay. so because a 13-year-old girl says it's okay, you do it? >> sir, please -- i'm not a really bad person, sir. please. >> as for that claim that he didn't say anything bad online, what about telling her he will perform oral sex on her or asking if she has ever had anal sex? have you ever had conversations like this with teenage girls on the internet before? >> no, this is my first time. >> you know, i hear that a lot. you can imagine why i'm skeptical on that? >> sir, please. virtually everybody who walks in the house the same thing. >> i'm sorry. >> i'm guessing that not everybody is telling the truth. >> sir, i'm sorry, sir. >> as we suspected, when he first covered his face, he knows there are cameras in the house. >> do you ever watch television? >> yes. i know, sir. >> you know what? >> this show, sir. >> the show? >> yes, sir. >> you have seen the show on television? >> yes, a couple of times. >> a couple of times. do you know what the show is called? >> "dateline." >> "dateline" what? "to catch a predator." >> sir, i'm not really a predator, sir. >> you are not a real predator? >> no, sir. >> just a pretend predator? >> no. i'm just curious. >> a curious predator?

>> i'm not really a predator, sir. >> so you saw those other shows we did? >> yes. >> then you probably know that i'm chris hansen with "dateline nbc" and you know the story we're doing? >> yes, sir. >> so is there anything else you'd like to tell us? we'd like to hear it. if not, you can walk out the door you came in. >> yeah, please. i'm sorry. >> and since he knows about our investigations, he probably knows what to expect when he steps outside. >> put your hands up. >> i'm not a criminal, sir. >> watch your fingers. >> i'm not a criminal, sir. >> clemente is arrested and charged with an attempted lewd act upon a child. he later pleaded no contest. both he and our earlier suspect who was in the backyard are led away to be processed. >> go to position two, open the door and call out. >> back at the undercover house a copy machine technician comes to the door. >> hi.

u.s. credit rating. timothy geithner says standard and poors showed terrible judgment. despite calls from republicans for him to step down, he says he's not stepping down. riots in london were sparked over a fatal police shooting. now back to "to catch a predator." do you want me to call for him? where is he? come on in! how was the drive? >> good. >> we hired this 18-year-old actress as a decoy. here, pretending to be a 12-year-old alone in our undercover house. the man who is coming to visit her is 29-year-old james cisneros. his screen name is too graphic to say on television. almost right off the bat sisneros asks an apparent 12-year-old online -- >> you like sex?

>> who doesn't? >> me, too. >> you want to hang out tonight? if you're not busy. >> she tells him that he can't come over now because her mother is home. >> oh, can you sneak off late tonight and we can get a hotel and i'll drop you off and you sneak back in? >> what for? >> sex. >> you heard that right. he wants to take someone he thinks is a 12-year-old to a hotel for sex. but the decoy won't budge. so he gives in and shows up at the house. >> so i made a drink. i don't know if you want to try it or not. it's kool-aid. >> is this regular kool-aid? >> yes. >> and he comes prepared. >> so what are you doing? did you bring condoms? >> yes. i got them right here. >> sweet. where do you want to -- just anywhere? >> it doesn't matter. >> why don't you take a taste of the drink there. please, have a seat. >> why? >> have a seat. >> no. >> i'm chris hansen. >> yeah. >> i want to ask you some questions. please have a seat. >> no.

>> i think that was our walker. definitely, that was our walker. there he is. >> as in our previous investigations, some of the men who arrive aren't coming to meet girls. >> clear. >> and we've prepared for that. this decoy is a 21-year-old actor pretending to be a 13-year-old boy. >> hey, come on in. >> how are you doing? >> tommy. nice to meet you. >> nice to meet you. >> what's going on? >> not much. what's going on with you? >> nothing much. listen, i made up some drinks. why don't you pour me some. >> meet 49-year-old rob colbertston, a computer web designer with the screen name web dev 2. he's been chatting online with someone who says he is 13. he lies about his age and says he's 40. and just like that earlier man, he tries to get the boy out of his house. >> you want to come over? >> maybe. if you're cool. >> i'm laid back, no pressure. >> but when the decoy, instead, suggests he come over to the undercover house, the man makes it clear what's on his mind.

>> let's meet. >> and? >> mess around. >> what's that mean? >> have sex. >> whatever he has in mind, we're about to find out. he lives close by and rode his bike to our undercover house. >> so what you up to? >> oh, nothing. i was thinking of actually getting in the hot tub. you think you might want to join me? >> that sounds cool. >> yeah? i'm a little nervous so do you want to go first? take your clothes off? then we'll get in? >> i'm kind of nervous myself, too. >> yeah? >> colbertston seems to have second thoughts. >> actually, i think i should probably be going. >> why? >> because i'm not comfortable with this. >> why not? >> because of your age. >> how was the walk over? >> walk was good. >> good. have a seat. what's your plan tonight? >> just out cruising around. >> just out cruising around. how old are you? >> 35, 40. >> 35, 40?

>> interlock your fingers. >> what's up? >> he pleaded no contest to one charge of an attempted lewd act on a child. >> go to position two and call out. >> back at the house, our female decoy is about to say hello to 27-year-old justin smith, a video post-production editor who does freelance work for nickelodeon, the cable network geared towards kids. using the screen name resident smith, he chats online to a decoy who tells smith she's a 13-year-old girl. after the decoy sends a picture, smith writes, it's definitely bad i think you're this cute, laugh out loud. the girl asks, how come? he writes back, because i'm 27. he sends her several naked pictures of himself. but the next day smith seems to express regrets. it can be dangerous, he writes. the girl asks, how come? smith replies, because it's illegal. over the course of 10 days, smith sends her links to 40

pornographic videos showing everything from oral sex to sex among multiple partners. he tells her when he comes over he wants to perform oral sex on her. and now here he is walking into the house. >> hey! come on in! how are you doing? >> good. how are you? >> awesome! >> good. >> i made us some drinks. >> awesome. >> and we have a hot tub. >> awesome. >> i really liked your videos, by the way. >> did you really? >> so how have you been? >> i have been good. it took me, like, 20 minutes to get down here because there was so much traffic. >> are you serious? where do you live? >> north hollywood. >> that's not that bad. >> we have a lot to talk about, you and i. why don't you have a seat right there, please. >> okay. >> i need to -- >> i have to go, i'm sorry. >> you're going to want to talk to me. trust me on this. you work at nickelodeon, huh? >> no. >> you don't? what's your name?

>> police! get on the ground. >> get on the ground. get on your knees! >> i'm so sorry. >> put your hands behind your head. back of your head. on your knees. both knees. >> i'm so sorry. i wasn't going to do anything. i swear to god. >> smith is taken to the processing center where a police investigator interviews him. >> i will be lucky if i have any sort of resemblance to my job my friends and my family, to the girlfriend i had, the daughter we have together. >> he knew coming in that what he was doing was wrong. that's why when he realized that he was caught and the ramifications on his life and everyone around him, in my mind, is why he became so emotional. >> smith later pleaded no contest to two counts. an attempted lewd act upon a child and attempting to send harmful matter. nickelodeon tells us they fired smith and he had no contact with children when he worked there. >> cell phone is off. i need the mix in here of the decoy. >> with all this technology, a house bristling with hidden cameras, microphones everywhere and 20 people crammed inside,

some glitches are bound to happen. as it did when one of our visitors arrived in his truck. >> hello? >> he's in the truck across the street. can you see it? walk down a little further. there he is. all right. hold on where you are. >> 24-year-old case, nicknamed matt, thought he was coming to see a 13-year-old girl. the decoy invites him inside. >> are you coming? how was the drive? >> he suddenly hears a walkie-talkie in the background. >> what? >> what's that? >> what's what? >> that sound? >> what sound? >> it was the decoy's walkie-talkie. instructions to her from inside the house were mistakenly broadcast in the driveway. he gets spooked but he circles around and comes in anyway. >> come in. why did you go away? >> because i thought you had something to do with police. >> i'm not that retarded.

>> online, screen name long beach dude 19 thought he was chatting with a 13-year-old girl. he tells her that he'll perform oral sex on her. i will show you heaven, he writes. i love it. i can do that all day. he asks if she's performed oral sex, asks if she's good at it and other specifics we can't tell you about here. remember, he's chatting with someone who said she was 13. >> what have you been up to? >> not much. >> do you want to have a seat or something? >> give me a tour. >> give you a tour? let's see. well, this is the hot tub. >> cool. >> we can hang out here. >> really laid back here. >> hi, matt, how are you? matt, i need to talk to you for a minute. why don't you have seat over there? but talking is not what he has in mind. >> put your hands up. hands up. both your hands up.

pp. >> long beach police, put your hands up now. >> he doesn't respond fast enough. the result is a taser shot. >> no! >> get on the ground. >> no! >> stop it. get him, cuff him. >> why was it necessary to use the taser on this guy? >> he has already demonstrated that he is not going to listen to the orders of the police officers. a lot of these guys, they are confronted with the reality that they're about to be exposed for what they did and a lot of them may try violence to get away. the taser was used to prevent any injury to him and also to any police officers. >> at the processing center, police find condoms in his car. he's pleaded guilty to an attempted lewd act on a child. coming up next -- a man who's been our house guest once before. do you remember? we talked once before.

way to the court system.

get on the ground! >> our undercover house in long beach is busy. 38 men are arrested over three days. but eight months earlier, during our previous investigation in riverside, california, this man, 26-year-old michael siebert, walked into our house. >> do you have a bathroom?

>> back then, seibert had a sexually explicit online chat with someone who told him she was 13, and he sent a picture of his genitals. hey, sir, why don't you come over here for a minute, please. seibert had some explaining to do. why did you spend pictures of yourself like this to her? >> oops. >> oops? >> i will never do it again. i promise. >> you say a lot of sexually charged things to her for a 13-year-old girl. >> i know what i did wrong. okay? >> okay. >> it will never happen again. >> go ahead, you can leave. >> sorry about that. >> okay. >> siebert told the riverside police that he gets treatment for seizures and the scar on his head was caused by a fall when he was an infant. >> do you work? >> yes. >> later he pleaded not guilty to a charge of an attempted lewd act on a child and attempting to send harmful matter to a child with attempt to seduce. he was convicted and sentenced to 18 months in state prison. so fast-forward eight months

from our house in riverside to our long beach investigation. he's still online, still using the same screen name and amazingly still chatting with someone who tells him she's 13. just like his chat eight months before he asks, have you ever had sex yet and i need sex. he also talks about group sex but is suspicious and asks, are you a cop? to which she replies, no, i'm not a cop. then apparently referring to his meeting with "dateline" eight months earlier he writes, i got caught before. incredibly he tells the decoy he has to delay the long beach liaison for a day because he has to go to court, a court date to face charges arising from our riverside investigation. but the very next day -- >> hey, come here! >> -- here he is. >> okay, we're not messing around with this guy. you do not let him get within six feet of you, eight feet of

you. >> who's all here? >> just me. >> oh. >> i promise. my parents are gone. >> you know, you look familiar to me. >> oops. >> that's right. oops, he's done it again. michael, right? >> oops, sorry. >> do you remember who i am? >> can i just go? >> what are you doing here, michael? >> i'm sorry. >> you were just in court on friday, right? >> um-huh. >> what happened in court on friday? >> he said more time. >> more time before the next court date? >> yeah. >> i'm sorry what i did. >> okay. but you've got to explain to me why or how you thought it was okay after having a court date stemming from our last visit and then within 24 hours you show up at this house to meet another young girl. what are you thinking about? now, you know -- >> i know. >> you know what you said online, right? >> yeah. >> how old is this girl? >> i don't know. >> 13. she told you she was 13.

>> yeah. and i told her to go away. she keeps im'ing me back. >> you ask if she's got naked pictures of herself. you ask if she performs oral sex and what color her underwear is. now, michael, you know it's not right to do this, right? >> i know. >> we had this same conversation in riverside, california. >> yeah. >> do you remember that? >> yeah. >> and right then you told me that you knew this was wrong and that you would never ever do it again. that turned out to be a lie, didn't it, michael? >> i promise this time if you rip it up, i'll never come back. >> but if he appears to be a sad cates case, accord ing to perverted justice, siebert has had sexual chats with at least three other decoys who said they were underaged girls. you should also know that there's another side to seibert's story. he served a year in jail for dangerous assault. >> what was the deadly weapon you used in the assault? >> a bat.

>> and who did you go after with a bat? some guy? is there anything else you want to tell me, michael? >> i know i did wrong. >> you did wrong. >> can i go? >> michael, you can go but i'm going to remind you that i'm chris hansen with "dateline" nbc and we're doing another story on adults who try to meet kids on the internet for sex. >> i know i did wrong. >> you can go right now and walk right out that door. >> any cops out there? >> that's not up to me, michael. >> yeah, it is. >> i'm not the police. so why don't you go ahead, michael. it's time to go. seibert clearly doesn't want to leave. having been through this before, he knows the police are waiting outside. >> [bleep]! i need a bathroom. >> michael, you're going to have to go outside. >> you i know. i hear them. >> now, walk out. walk out.

get on your knees. >> like the others, siebert is charged with attempted lewd act on a child. he's pleaded no contest. his lawyer says he has severe mental issues. is that a defense in any way in this case? >> in my mind, no. it's not a defense. he knows what he did was wrong. he knew enough that when you confronted him his first words were "oops." he knew enough to promise you that he wasn't going to do this again. >> do you live with your mom? >> yep. she's going to kill me. >> he admitted in our interview that he had been previously convicted of assault. >> yes. >> what does that say about the danger he could present to a young teen home alone? >> my biggest fear is that he would show up, the young teen would decide not to go through what they were talking about in their internet chat, he would become frustrated with that and his violent nature would come out. >> seibert was convicted on the long beach charge.

over the course of three days, 38 men were arrested in the investigation. that's a large number of suspects, but the long beach police were ready. that's a large number of suspects. did that seem like a big number to you? it's our second highest number we have ever seen. >> given the amount of population in this area, it's coming up, meet more men who come up our driveway in long beach like this man, when he arrives at our house he seems to have second thoughts. >> so what you doing? >> nothing much. i was just talking online. >> the question is, will he finally come inside? and for the first time since we've been doing our investigations, the police will set up in a nearby park where a

suspect may be thinking he can lure a young teen into his car. >> everybody on this? >> back at the house, things will still get busy. how you doing? why don't you have a seat right there on that stool. are those your friends outside? with some trying to make a getaway. >> take him. he's running. >> but the police will have other plans. >> get on your knees now! >> you'll find some guidelines on how to protect your kids against online predators on dateline.msnbc.com. >> that's all for now. i'm ann curry. >> i'm stone phillips. for all of us at nbc news, thanks for watching.
